It may happen that the radiographer may wish to send out prints fromthe plates—these, when of full size, are too bulky for convenient use ; inorder to reduce the inconvenience to a minimum I have had prepared forme a large viewing box which will accommodate six plates, 15 by 12 Convenient blinds are provided for screening purposes ; the six platescan be reduced at one exposure to a whole or a half-plate size. When aprint is made from this plate the complete record is now ready for the surgeon,and may take the place of the tracings described above or may accompany. Fig. 284.—Elevation of table-eud. 336 EADIOGRAPHY them when both are required. The surgeon is now completely independentof the original plates—these are, therefore, stored away and may notbe required again, except when questions of detail arise. The set oftracings, negative and print, are also stored in an envelope, indexed, andplaced in the filing cabinet. The chief object of this technique is to provide a convenient record ofradiographic work for the use of the physician or surgeon, but there areother conveniences, chief of which may be that of the radiologist, for whenhe comes to compare a large number of cases the prints obtained of thecomplete examination are most convenient; he can carry a hundred or twoof these records, and when comparing the sets they are much more con-veniently handled than the original plates.
